Infrequent Errors (1 or 2 discrepancies in 30 trials): Some CDs which aredetected as ISO9660 (or at least, not specifically detected as anything else). These were Windows 95 Upgrade, Calendar Creator 5.0, Photoshop 4.0.1, NortonUtilities 2.0 for Win95. These errors are not necessarily consistentlyproducible, so many of the above CDs may have also produced errors, if enoughtests were run.

Specifying the -o nojoliet option to mount didn't help on any of the CDs witherrors, except for the Win98 Joliet 3 CD. -o norock didn't help either for alllisted CDs. Compiling the kernel without Joliet support produces noimprovement, the errors still occur on all the listed CDs. It also doesn'tmatter whether I use the ATAPI drive or the SCSI.

As for the one Joliet 3 CD, errors on the Win98 CD were difficult toreproduce - without the nojoliet option, sometimes I'd go through a wholeseries of 30 tests with no errors, other times almost every test had adifferent value. With nojoliet, however, I got no errors, period.I made an image of the most error-prone of my CD-ROMs onto my second harddisk. The disk was M$ Office 2000 Standard Upgrade. It registers as Rockridge(and not Joliet, I checked). I then ran this sequence of commands severaltimes:
